Also keep in mind that, if you use a retipper rather an ZYX, the dimensions of the stylus block as well as how the stylus block is affixed to the cantilever will differ, along with the shape and dimensions of the stylus sections that contact the LP groove.
In the ZYX cantilevers and stylii (made by Namiki), the end of the cantilever rod is planed down to an acute angle (less than 30 degrees), creating a flat surface which is what the stylus block is bonded to. The stylus block can be both small and short, and therefore of very low mass.
In the Ogura-made cantilevers and stylii, a longitudinal, vertical slot is cut through the end of the cantilever rod, and the stylus block is inserted into that slot and bonded in place. In recent years, some manufacturers have added a thin metal plate to the slot to reinforce the bond. In this type of design, the stylus block is longer than the Namikis (since it has to reach through the cantilever), but the stylus block width is generally a small fraction of the cantilever diameter (less than 1/2), so the stylus block mass can be of fairly low mass.
In many recent cantilevers and stylii of European origin, the end of the cantilever rod is chopped off at a right angle, leaving a flat round surface to which the stylus is bonded. In these designs, the stylus block is long (since it has to reach through the cantilever), and it is also as wide as the cantilever rod, so the mass of the stylus will be higher than with either the Namiki or Ogura designs.
To retip a cartridge that was originally equipped with a stylus made by one manufacturer with one made by a different manufacturer is like rebuilding a Porsche engine with Jaguar pistons and crankshaft - the components used for rebuilding may be of high quality, but the design philosophy is rather different from the original.
Still, as one poster wrote above, changing only the stylus will alter the sound less than if the cantilever material is changed. When a cartridge is designed, the designer will consider the moving mass (sum of the stylus, cantilever and coils), the resonant character of the cantilever, and the (sonic) propagation velocity of the cantilever (affected by the cantilever's mass and rigidity), then choose the suspension and dampers accordingly. If you change the cantilever material, you are effectively throwing the original designer's calculations away.
There is much more (far more than what I have written above) to rebuilding a cartridge than affixing a new stylus or altering the cantilever. In over 30 years of involvement in the phono cartridge industry, I have not seen one retipper who has presented the entire story, who has effectively said "Here are the all of the considerations. Here are the cons as well as the pros. Make a wise choice that is best for you".
BTW, when ZYX replaces the Airy 3, there is a reasonable chance that they will incorporate any improvements and refinements which they have learned over the past 5 years. You may want to inquire about that.
kind regards
